HMS Erin. Inner

Ref: HLSS/004

History

This is what is left of HMS Erin, a 394-ton anti-submarine trawler, which was sabotaged in February 1942, whilst tied up inside the South Mole. It was later broken up and dumped in its present positions, in order to clear the mooring.

The site has been registered under the Nautical Archaeology Society’s ‘Adopt a Wreck’ scheme and we have spent over two years surveying and researching the vessel. Full details of this work are given in the Chapter ‘The Inner and Outer’ – a Detective story’.

Layout ‘Inner’

The ‘Inner’ is the lower part of a bow section. It lies upright on a slope, between 16 and 24 metres deep, with the bow lowest and is 2 metres high. The rear part is a flat deck, with hatches showing tanks and piles of firebricks beneath. The forward part is open, with cross beams and the base of a gun mounting post sticking up. The entire section is covered in colourful gorgonians and is home to many crustaceans and small fish.

Diving the Wreck

It may be dived by boat, or via a high entry off the Detached Mole, swimming back inside the Mole to exit. This is useful when the sea is choppy. You can dive either site, or both together. From the bow of the ‘Inner’, follow a compass bearing of 210 degrees. Two thirds of the way along, you should pass a very large anchor – keep this just on your right and you should soon pick up the Outer. Sometimes a line is tied between the two sections.

The ‘Inner’ often has fishing lines caught on it and the ‘Outer’ sometimes snags nets, so watch out for these. Both sections may be entered, but room is limited. A small torch is useful if you penetrate.

The area occasionally suffers strong currents, so use a shot, particularly for the Outer. Carry a delayed SMB and be aware that you are quite close to the busy harbour entrance. You may wish to work your way up to the slope towards the end of the dive. This has lots of life and interesting rubble on it and rises up to only 6 metres, so is the ideal place to continue your dive, whilst doing any stops.

Both sections are enjoyable dives and offer a lot to those interested in wrecks, photography or marine life.
